However, this mark is not construed as meaning：In certain embodiments of the present invention, they are only options or optional Operation and/or the frame with solid-line boundary are not optional.

In the following description and claims, term " coupling " and " connection " and their derivative can be used.It should Work as understanding：These terms are not intended to as mutual synonym." coupling " be used to indicate two or more elements can with or can Not contact physically or electrically, cooperate or interact with directly with one another." connection " is used to indicate in coupled to each other two or more Communication is established between multiple elements.

As it is used herein, virtual machine (VM) is the software that operating system and application are run as physical computer. Multiple VM can be run in same host system simultaneously.

Cloud service provider is dedicated to providing powerful and total solution for client, realize as far as possible it is full-automatic, Without or seldom manual (i.e. manpower) is only needed to work.However, observed current offer cloud framework service is One defect of system (for example, infrastructure is service or IaaS providers) is that they cannot be provided to the serial of virtual machine The automatic remote of port accesses.Serial port is virtual hardware element important in VM, just as Ethernet Adaptation Unit, hard disk driver, in Central Processing Unit, memory etc. are the same.A kind of most common use of serial port is for debugging and/or configuration purpose, middle pipe Reason person can be connected to equipment to obtain the access set to advanced configuration using serial port.

As more complicated cloud application continues to develop, need for the virtual port of VM to be fully integratible into the cloud system of provider (realize Self-Service and automation) becomes extremely important.

But it is problematic to the current techniques of the access of virtual serial port for providing.For example, some are current Business system does not support virtual machine serial port even.And virtual serial port can be configured for connection to by other business systems Physical serial port on host, the file being mapped on host or with operate in another virtual machine on same host or Using being directly connected to.However, these methods are problematic for modern complicated cloud application, these cloud applications potentially use Multiple VM to act in concert, these VM can be placed on different host (i.e. server computing device), and can be on ground It separates in reason and is therefore performed in different websites.In addition, these business systems are substantially to concentrate, it means that Mei Gexu Plan machine is required for being configured to be directed toward external equipment, and so as to create the environment of a shared component, this environment is susceptible to bottleneck And safety problem, needless to say it is Single Point of Faliure/maintenance.In addition, these solution speed it is slow, it is not expansible and usually not It corresponds to reality, because a large amount of human input (for example, for other equipment to be set or configured) is may relate to, and the VM disposed Position may not be static or known or possibly even change over time (for example, passing through migrating technology), thus need volume Outer configuration work.

Therefore, can meet without any solution in the market growing to automatic, powerful, safe and quick visit Ask the demand for quickly entering potential in technology and geographically different VM used in the modern complication system in high in the clouds.This Outside, there are no solution can support completely by need serial port access multiple VM form cloud application (for example, VApp Self-Service).For example, current system in the outside of the cloud application of deployment, needs static configuration, do not support to realize and continue The bottleneck of large-scale environment is concentrated and is easily become in integrated automation, it is difficult to management/maintenance in large-scale environment, and it is necessary It sets to provide function at each deployment website.In addition, it can easily support that the VM's disposed is fast there are no solution Speed migration, while continue to support serial port connection.

Therefore, disclosed herein is certain accessed automatically of serial port that can provide the VM to " Self-Service " cloud application A little technologies.Therefore, embodiment can provide instant, the private access of the serial port of the VM to one or more deployment, with example Such as create completely isolated testboard.

Fig. 1 is to show the coordinating agent disposed in cloud application and virtual serial port concentrator in accordance with some embodiments The high level block diagram used of module.Fig. 1 shows system 100, including user 102, the client that can be used by user 102 Computing device 104 (such as according to configuration or program it is at least semi-autonomous operated) and one or more server meter Equipment 106 is calculated, which includes cloud management module 108, coordinating agent 112 and including virtual serial port The cloud application 114 of the deployment of concentrator (VSPC) module 120.

In some embodiments, VSPC modules 120 can be provided together with the VM images of cloud application 114 in cloud application template In 110 (for example, vApp templates, it may be possible to the catalogue for the multiple template that can be used) so that when cloud application template 110 is by user 102 select and are disposed as cloud application 114, and VSPC modules 120 can be provided rapidly and easily to as identical cloud application The private access of the VM 116A-116N of 114 part deployment.

In some embodiments, Configuration Agent 112 (for example, finger daemon etc.) can be configured as " monitoring " or with other Mode identifies the cloud application 114 disposed, and detects that the VM 116A-116N of cloud application 114 have arrived at " RUN " state (example Such as, it is " online " and at least partly operable), and the serial port of VM 116A-116N is caused to be configured such that they connect It is connected to VSPC modules 120.VSPC modules 120 can distribute local port to allow attachment in the VM 116A-116N of its connection Each, and can safeguard (or more generally, the identifier of port-it may or may not be several of port numbers 126 Word) 127 associated Mapping data structure 122 of identifier with VM116A-116N.In some embodiments, Configuration Agent 112 Some or all of the map information can be provided to user 102, client computing device 104 and/or cloud management module 108 (and possible other information, the reachable IP address in the outsides of such as VSPC modules 120).Therefore, client computing device 104 (or another computing device) can utilize the map information (for example, port numbers associated with VM 116A) and VSPC modules 120 outside ip address 124 obtains the access of the virtual serial port to the VM 116A, VSPC moulds via VSPC modules 120 Block 120 can relay (or forwarding, routing etc.) serial port business between client and VM 116A.

Advantageously, therefore each user can be quickly obtained themselves completely isolated cloud application, these clouds should It is accessed with external IP and the different ports of VSPC modules 120 via deployment that can be via each VM (for example, using Telnet or Secure Shell (SSH)), to reach the serial port of VM.In addition, user can restart its dedicated VSPC mould Block 120 is without any other user for influencing to dispose in cloud or application.Further, since each user obtains the special of themselves With VSPC modules 120, therefore performance is relatively preferable, and the solution can be completely portable across each website, because it is not Dependent on the outside/physical serial port concentrator disposed and be configured in remote site.In addition, cloud application can easily will be complete Portion's function exports to long-distance cloud, and the VM of cloud application can be easily from an equipment transportation to another equipment, and VSPC moulds The function of block 120 and/or Configuration Agent 112 can be realized using lightweight software (for example, small-sized Linux types VM etc.).

Therefore, in some embodiments using cloud application template, user's (and automation tools) can be from catalogue Selection cloud application template starts it to create cloud application, and in many ways in either type (such as via cloud application member number According to (for example, being provided by cloud management module 108) and/or via e-mail or short message service (SMS)) obtain serial port and visit Ask information ,/test/debugs its application so as to which user be allowed to be initially configured, so as to fulfill people and/or automatic test (as continued It is integrated).Therefore, it is necessary to access the user of cloud application serial port access no longer to need by static test bed, worry that performance is asked Topic or the maintenance for performing underlying device；On the contrary, these users can use now supports that the VM's with serial port connection is true Positive cloud Self-Service product.

Fig. 1 is returned to, user 102 can be interacted using client computing device 104 with cloud management module 108.Client Computing device 104 can be any equipment in the various equipment with calculating and/or network function, including but not limited to portable Formula handheld device (for example, cellular phone or tablet computer), wearable device (such as GoogleDisplay), it is general Personal computer or laptop, workstation computer or other kinds of electronic equipment, such as thm-client computing device, Games system, personal messages transceiver of network-connectable etc..

Cloud management module 108 is the one or more modules for the ability for providing management cloud or data center resource to the user Group.For example, cloud management module 108 can to user 102 provide web interface/entrance (or client computing device 104 should With routine interface (API)) with allow user's selection, create, editor has disposed or the cloud application 114 that will dispose etc..About cloud The further details of management module 108 will be provided later in reference to Fig. 2 herein.

Therefore, at circle " 1 ", client computing device 104 can use API or web portal order 150 and cloud management mould Block 108 interacts to dispose cloud application 114.For example, cloud management module 108 can store one or more including VSPC modules 120 A application template.User 102 can be by allowing client computing device 104 to send API or web portal to cloud management module 108 Order 150 a template is selected to be disposed.

Cloud application 114 can be any one of various types of applications of various forms.As an example, Yun Ying Can be vApp with 114, be the group (can be managed as single object) of one or more VM, can by network into Row communication (can be isolation), and resource and the service in deployed environment can be utilized.Therefore, cloud application 114 can be The considerably complicated multilayer application realized by multiple complementary VM.VApp is considered the container of VM, is these VM provides resources control and management --- for example, the portable self-contained unit comprising multiple VM, typically comprises multilayer application (such as Web server, database and security server).VApp can provide resources control for the VM in container and define network Configuration.VApp can be highly convenient for carrying, because all the elements included can be transferred to another Virtual base facility, And electricity can be opened, power off, hang up, close and/or clone entire vApp.

In some embodiments, cloud application 114 can be instantiated by cloud management module 108 from application template 110.At some In embodiment, 114 template of cloud application (for example, vApp templates) be loaded with operating system, using and possible data void Plan machine image.Cloud application template 110 ensures that VM is consistently configured across entire tissue or across multiple users.In some embodiments, VSPC modules 120 are included in a kind of infrastructure component as application in cloud application template --- that is, not being directly to provide A part for 114 desired function is applied by the particular cloud of template definition.

Therefore, at the circle of Fig. 1 " 2 ", cloud management module 108 instantiates (152) desired cloud using VSPC modules 120 should With 114.Therefore, it (is such as represented according to the definition of cloud application 114 by corresponding application template 110), cloud management module 108 will cause For one or more VM116A-116N and VSPC modules 120 according to application template 110 " startup " (or execution), application template 110 can To include starting sequence and various configurations.As shown in the figure, each in one or more VM116A-116N includes serial end Mouth interface 118A-118N.However, it is not that each VM 116A-116N are required for connecing with serial port in various embodiments Mouth 118A-118N, and in some embodiments, one or more VM 116A-116N can have more than one serial end Mouth interface 118A-118N.

At circle " 3 ", coordinating agent 112 can detect that some or all cloud applications 114 come into " RUN " state. For example, in some embodiments, coordinating agent 112 can detect when the particular VM 116A of cloud application 114 has succeeded It " startup " and is ready for operating, and in some embodiments, when coordinating agent 112 detects entire cloud application 114 Succeed " startup ".

As shown in circle " 3 ", coordinating agent 112 in the embodiment depicted is communicated with cloud management module 108 with to fortune Capable cloud application 114 carries out this detection.For example, coordinating agent 112 can perform " poll ", such as to cloud management module 108 Request (for example, API Calls, function call etc.) is periodically sent, whether new cloud application 114/VM 116 is indicated with request It comes into the response of operating status or describes the execution of all cloud application 114/VM 116 under the management of cloud management module 108 The response of state.In other embodiments, cloud management module 108 is can be configured as in itself by certain notices " push " to coordination Agency 112.For example, cloud management module 108 can be configured as whenever particular cloud using 114 (or its any cloud application 114 or its son Component) change state or send notice when entering " RUN " state.As another example, cloud management module 108 can by with It is set to the notice for the execution state for periodically sending the one or more cloud applications 114 of description or its sub-component.

In response, coordinating agent 112 can interact the serial end so that VM 116A-116N with cloud management module 108 Mouth interface 118A-118N is connect with VSPC modules 120.For example, coordinating agent 112 can interact to obtain with cloud management module 108 The details (for example, list of its VM) of cloud application 114 is taken, identifies the VSPC modules 120 in cloud application 114, identifies VSPC modules 120 IP address 124 (for example, outside ip address), and Indicated Cloud management module 108 is being enclosed VM 116A-116N at " 4 " Serial port interface 118A-118N connect with VSPC modules 120.As a result, in some embodiments, VM 116A-116N will taste The connection 162 with VSPC modules 120 is opened in examination.

Local port can be distributed at circle " 5 " for 162, VSPC of each connection modules 120 for receiving from it The serial port related service of the serial port interface 118A-118N that should be sent to VM 116A-116N of his entity.Then, VSPC modules 120 can be by the identifier of the port (for example, port numbers 126) of distribution and the identifier 127 of corresponding VM 116A (for example, socket identifier of host name, the IP address of VM 116A, associated connection 162 etc.).In some embodiments, the pass Connection information is stored in Mapping data structure 122.The Mapping data structure 122 can be saved (for example, be stored in flash memory, In hard disk etc.) in the nonvolatile memory.In addition, this can allow to exist in same cloud application 114 (for example, vApp) next time Restored to map, and client VM 116A serial ports 118A can be supported from VSPC moulds when " power-up " again after stalling The previous reserved port of block 120 is individually disconnected and/or is reconnected therewith.

At this point, at circle " 6 ", coordinating agent 112 can obtain map information 156 from VSPC modules 120.In some implementations In example, VSPC modules 120 are configured as reporting the information to coordinating agent 112 when establishing (or periodically) and establishing new association 156, but in some embodiments, coordinating agent 112 can alternatively from VSPC modules 120 ask the information 156 (for example, Pass through poll etc.).In some embodiments, map information 156 includes the local port number 126 of associated distribution and VM identifiers 127。

Optionally, at circle " 6A ", coordinating agent 112 can provide back the map information 156 to cloud management module 108 (for example, to update the 114 associated metadata of cloud application with disposing) so that other modules or equipment can determine it is fair Perhaps the port numbers 126 of serial port interface 118 are accessed via cloud management module 108.For example, circle " 7B " at, may with The client computing device 104 of cloud management module 108 (for example, using Web portal or API) communication can be provided to from cloud pipe The connectivity information 157 of module 108 is managed, map information 156 can be included and the IP of VSPC modules 120 may be included Location.Alternatively, or in addition, at circle " 7A ", coordinating agent 112 can export/provide connectivity information 158.It can be to client Hold computing device 104 (for example, in Email, SMS, sending out notice) or user 102 (for example, via another computing device, Via display equipment etc.) information 158 is provided.Include the connectivity information of map information 156 later with reference to Fig. 4 offers herein A 158 possible example.

At this point, client computing device 104 can by using IP associated with desired " destination " VM 116A Location 124 and certain port number 126 are come communicate with VSPC modules 120 (for example, being sent to grouping 160), thereby using reception Connectivity information 157/158 is connected to the virtualization serial port interface 118A of desired VM 116A.For example, client calculates Equipment 104 can carry the grouping 160 of agreement proper data by sending in the ip packet and communicate to start telnet or SSH (or other agreements), the use that IP groupings have the destination IP address 124 of VSPC modules 120 and distributed by VSPC modules 120 In the destination port numbers 126 for reaching VM 116A.

Once receiving grouping 160, VSPC modules 120 using Mapping data structure 122 can determine that 160 will be grouped Where be sent to.For example, VSPC modules 120 can be performed using the port numbers of the grouping received to Mapping data structure 122 Lookup to search for appropriate ports number 126, and identify associated virtual machine identifier 127 (for example, host name, IP address, Socket identifier etc.), which can be used to determine grouping 160 should be sent to where.

Fig. 2 be show it is in accordance with some embodiments about the coordinating agent 112 of Fig. 1, VSPC modules 120 and cloud management module The block diagram 200 of 108 further details.
